> When hadoop lists object in versioning bucket with many delete marker in it,
> OSS will return
> {code:java}
> <?xml version="1.0" encoding="UTF-8"?>
> <ListBucketResult>
> <Name>select-us-east-1</Name>
> <Prefix>test/hadoop/file/</Prefix>
> <Marker></Marker>
> <MaxKeys>100</MaxKeys>
> <Delimiter>/</Delimiter>
> <IsTruncated>true</IsTruncated>
> <NextMarker>test/hadoop/file/sub2</NextMarker>
> </ListBucketResult>
> {code}
> It sets *IsTruncated* to true and without *ObjectSummaries* or
> *CommonPrefixes*, and will throw FileNotFoundException
> {code:java}
> // code placeholder
> java.io.FileNotFoundException: oss://select-us-east-1/test/hadoop/file: No
> such file or directory!java.io.FileNotFoundException:
> oss://select-us-east-1/test/hadoop/file: No such file or directory!
> at
> org.apache.hadoop.fs.aliyun.oss.AliyunOSSFileSystem.getFileStatus(AliyunOSSFileSystem.java:281)
> at
> org.apache.hadoop.fs.aliyun.oss.TestAliyunOSSFileSystemContract.testGetFileStatusInVersioningBucket{code}
>
> {code:java}
> // code placeholder
> ObjectListing listing = store.listObjects(key, 1, null, false);
> if (CollectionUtils.isNotEmpty(listing.getObjectSummaries()) ||
> CollectionUtils.isNotEmpty(listing.getCommonPrefixes())) {
> return new OSSFileStatus(0, true, 1, 0, 0, qualifiedPath, username);
> } else {
> throw new FileNotFoundException(path + ": No such file or directory!");
> }
> {code}
> In this case, we should call listObjects until *IsTruncated* is false or
> *ObjectSummaries* is not empty or *CommonPrefixes* is not empty.
